Video looks as it it's interlaced

[Chris Tapp]

I’ve upgraded a system from 1.4.5 to 1.8.1 and everything works as expected except that the video looks as if it has interlacing artefacts after the stream has been running for some time (not sure exactly how long, but several hours).

The effect is hard to describe, but it looks very similar to the horizontal jagged-edges that video has when horizontal motion is present in an interlaced stream.

The pipeline is using playbin to capture frames from a DVB-T source (generated by MuMuDVB) and makes them available to the application using “appsink" - the same source looks ok when viewed using VLC.

Any ideas what could be causing this or what I should look at to understand what’s going on? The system has limited memory / disk resources, so I’ve not been able to capture anything using diagnostics that gives any clues.
